Section STYLOPSIS A. Adams. 

 Eulimella (Stylopsis) resticula n. s. 



Shell extremely small and thin, with a minute upturned sinistral nucleus 

 and eight swollen yet laterally flattened whorls. The shell is without lustre, 

 of a waxen white, translucent, the gray mottled with black and yellow of the 

 dried animal shining through the shell. Sculpture entirely of even fine spiral 

 close-set microscopic grooves, covering the entire surface. Coil, as it were, 

 pulled out and closely wound like a "stranded" rope; whorls laterally slightly 

 compressed, but swollen in front of the suture and so having a turrited look ; 

 base elongated; aperture rounded in front, narrow but rounded behind, the 

 margins and slightly arched pillar simple and continuous except over the body. 

 There is no umbilical chink or depression, nor any plait on the pillar. Lon. of 

 shell, 3.5; lat, 0.7 mm. 



Habitat. Rare on the sand flats between tides at Key West, Hemphill. 



A singularly frail and odd-looking little shell.

 Type of the subgenus. 



Habitat. St. Thomas (Riise), Morch. Beach, Sarasota Bay, W. H. Dall. 



This curious little shell is like a minute slender but few-whorled Turbonilla, 

 thin, white, with no ribs, spirally closely grooved. Watson's figure of his 

 Mucronalia xanthias is a good representation of our shell, except the mouth,
